Обсуждение: getArray/setArray - desperately need to know how the implementation is done

Don't know if arrays are handled by the pgsql driver or not, but if not
you could always de/serialise the array to/from a blob.

> I need to store and retrieve arrays as they are . JDBC 2.0 provides methods getArray/setArray which facilitates this.
Buti couldn't find out how exactly it is implemented. 

The reason why i am going for the getArray/setArray methods, is to make use
of the Arrays provided by postgres - so that i could use the same in
querying an array field. This i think would not be possible if i were to
store the array by serializing it.

The "pgjdbc2.jar" jdbc driver api that i picked up from the Postgres JDBC
site does provide an implementation of the java.sql.Array interface. But i
couldn't figure out how exactly i could use this implementation. Infact
there is no documentation from the Postgres JDBC site on the usage of these
api's.

Has someone used these API's, and made use of the Array implementation here.
If so please do let me know of its usage.

Narayan Murthy.
